Specification of Letters Patent; Patented July 28, 1914:.

Application filed March 18 1913. Serial No. 755,229.v

that type of torches wherein a vapor ordi-' narily a product from gasolene is supplied under pressure, and is especially adapted to the torch shown in patent issued to me J an. 6th, 1903, No, 717,831.

The object of the invention is to provide a torch capable of delivering vapors under pressure at distances from the generating part of the torch and also to increase the capacity and eiliciency of the torch.

The details of carrying out this invention as well as other details of the invention will appear more fully from the specification The invention is illustrated in the accompanying drawings as follows Figure 1 shows a central vertical section through the torch. Fig. 2 a central section of the resisting valve to the secondary coil, the section line being marked 2, Fig. 1.

Fig. 3 a section on the'line 3-3 inFig. 1.

1 marks the'base and 2 the burner and reservoir support mounted on the base. A cylindrical wall 3 rests on the support 2. An inner wall lwith an annular bottom 5 and annular top 6 form the walls of the fuel reservoir 7. A fuel pipe 8 extends down into the reservoir and connects with the coil in the combustion chamber. The coil discharges to the vapor controlling connections 10 at the top of the device. A hose or flexible tube 11 is attached to the connection 10 and conveys the vapor to the burner 12, the burner being supported by any suitablev support as 13.

In order to utilize the burner at distances from the generator it is necessary to use flexible tubes and the nature of the material forced through the tube ordinarily requires thls type to be made of metal and in order to maintain the desired flexibility of this tube,

tubes of' very small capacity only can. be

used and where the burner is at considerable distances from the generatorvapor can be forced to the burner in sufficient quantities only by-a high pressure at the generator.

The pipe is connected to a bypass 14 on the vapor controlling connection 10 and conveys vapor to the mixer 16 for the burner 17 for the generating portion of the torch. This pipe 15 is carried from the vapor controlling connection to the mixer 16 through the combustion chamber. This protects the pipe 15 and also heats the vapor going to the auxilliary' burner 17 I A pump barrel 18 is provided with a plunger 19 completing the pump and the plunger is operated by the lever 20, the lever being fulcrumed at 20 and secured to the plunger by apin 20 The inlet passage 21 is connected with the pipe 21 which has the downwardly extending loop or extension 21 which can be readily inserted into a receptacle containing liquid fuel. By operating the pump plunger, liquid is drawn into the pump barrel past the check 21 andis di scharged by the passage 22 leading to an upright passage'22 and a lateral passage 23 leading to the reservoir 7. The passage 22 is valve controlled and checks 2 1 and25 are provided for preventing a return, flow of the liquid forming a part with the check 21 of the valve system of the pump.

A coil 26 is arranged within the coil 9. It is connected through a fitting 27 with the top of the reservoir 7 and connected with a loop 28 with a fitting 29 leading to the connection 23. A check valve 30 is arranged in the fitting 29 and a movement of the check valve is resisted by a spring 31 (see Fig. 2). The connection 23 is in a fitting 23. This has a ring 32 which surrounds the pump barrel and this forms a support for the pump barrel. -A valve 33 is arranged in the wall of the fitting 23 and operates in the passage 23 (see Fig. 3) so that the resistance of the flow of liquid through the passage and connection 23Imay be regulated. A cap 34.- is arranged over the valveso as to prevent any unintentional change in the adjustment of this valve. It will be readily seen that by partly closing the valve 33 a resistance may be formed to the passage of liquid to the reservoir 7 and where this happens a portion of the liquid will pass by way of the valve 30 to the coil 26.

Where great capacity is required or great pressure is required the quantities of fuel delivered to the reservoir 7 are suflicient to cool it so as to prevent the rapid production of vapor in the reservoir 7 and where this occurs the pressure and quantity of gasolene delivered to the coil 9 is reduced. In this way the capacity is not as great as desired nor is the pressure what is desired. Under these conditions the valve 33 is slightly closed obstructing the passage of liquid through the connection 23 and in this .way the fuel is forced by way of the valve 30 to the coil 26. It will be understood that this coil 26 ordinarily has so little liquid delivered to it that it acts as a flash coil and delivers the vapor so produced to the top of the reservoir 7. By adjusting the valve 33 practically any pressure that may be desired can be delivered to the reservoir 7 depending on the amount of liquid passing the valve 30 and delivered to the coil 26. hen the nature of the use is such that this additional pressure is not required, the valve 33 is fully opened and the slight elevation of the loop 28 together with the resistance of the spring 31 prevents the passage of any efiective quantity of fuel to the coil 26. Under these conditions, the device will operate in the same manner as though the coil were not provided.

In order to prevent the creation of vapor in the pump which interferes with the proper action of the pump, I provide the pump barrel with a series of radiating rings 18 These are in the form of disks having flanged openings pressed in them and these are on the pump barrel as shown.
